Application filed April 26, 1910. Serial No. 557,676.

To all 'whom it may concermf Be it known that l, HEINRICH Korrnns, engineer, residing at lsenbergstrasse 30, Essen, Germany, have invented a certain new and useful Improved Closing Means for Ovens, of which lthe following is a specifcation.

rlhis invention relates to closing means for ovens, its object being to provide an ehcient substitute for Winches and jacks which travel along the roof of the oven-battery, over thedoors, for the purpose ot hoisting and opening sama rlhese Winches and jacks have the disadvantage that they, and the lmen kworking them, are exposed to risk `of falling from the ovens, and also to the action ogas and vapors which are highly inconvenient to inhale, and in course ot time injurious to metal. Moreover, the presence of the tracks at front and rear of the root renders it necessary to place the mains between them, and the available space on the roof is thus considerably restricted. 'lhe present invention obviates these disadvantages, and primarily 'consists in removing and replacing the doors by means ot, a hoisting and traversing jack which is moved on a carriage in front of the doors, 'and has means for engaging the doors. By means ot this jack the door is engaged, hoisted and eased, and then withdrawn by traversing the jack on the carriage, which can then be moved along the track to expose the dooraperture. 1With a traveling jack of this kind there is less liability to tilting, and the Workmen are less exposed to the gases. @nl the push-engine side ot the oven-battery the elevated track, with the jack jack may be mounted on the same carriage with the push-engine. @n the coke-bench side the carriage may carry a platform ex tending across the track, to serve as a bridge for the expelled coke, guidewvalls being erected at the sides of the platform, across the carriage. 0r to obviate the necessity for this or an equivalent bridge, and for sinking the track below the door level, the carriage on thecoke-bench side may travel 'on' an depending in front ot the doors. The main or mains may be mountedon the trame-work on which the track is laid, clear ci the roof.

Two constructions embodying the arrangements described are shown in 'the annexed drawings, in Figures l. and 2, and

3 and el respectively, Fig., l being a front vof the oven doors. A carriage f driven by a motor g vruns on the rails, and` carries a hoistlng jack it on guides on which thejack can be reciprocat-ed by means of a screw z', suitable gear being provided enabling 'the' screw to be coupled withthe motor. lifting member Z of the jack is slidable in vertical guide-slots 7c, and is operated by means of a crank and toothed gear mi' rlhe member Z has dogs n arranged in a common vertical plane and adapted to enter sockets o provided onthe face of the iron structure` 7) of the oven doors, a. rlhe carriage also has a platform g, forming a kind of bridge across the track, and a high wal-l r extending across the carriage is erected at each side of this platform. rlhis platform extends over the track infront of the open oven, and permits the coke to be readily-.pushed out of the latter over the track and without spreading to the jack. For opening an oven the carriage is run in front of same, so that the jack is opposite the door, and the jack is then tirstreciprocated, to` place the dogs n under `the sockets 0, secondly operated to slightly raise and ease the door, and, then traversed to remove the door from the frame. rlhe carriage, carrying the door, is then moved along the track so that the platformtion and in true parallelism with. the door frame While being-removed from or inserted into the latter in a direction parallel to the longitudinal axis of the coking chamber, so that any edging and jamming of the door more particularly previously to becoming properly seated-within its frame is @Eecroo p los above the doors, enables the gas main t to be mounted on the frame adjacent the edge of t-he roof, the ascension pipes u being bent over to ]oin the main. Practically the en? tire roof is thus clear for charging purposes.

In the modification shown in Figs. 3 and 4: the frame c supports in addition .to the main t an auxiliary main fv, to Which connection can be made by means of a pipe :v carried by a tackle traveling on a rail fw. The carriage f is'in this case mounted on an elevated track e, in the manner of a traveling crane, and the jack h depends from the carriage, on which it can be reciprocated by means of the motor .57. The jack is in this caseoperated from the ground, its function beiig similar to that described with 'refer ence to Figs. 1 and 2. l i

What I claim 'as my invention and desire to secure by Letters Patent of the United States is:-

.1. A device of thev character described, comprising an oven having a plurality of horizontal coking chambers, door frames at the mouths of said chambers, doors fitted into said frames and provided at their front with engaging means, a lifter adapted to travel in front of said doors and provided With means adapted to successively coperate with the engaging means of the doors, said engaging means and means on the lifter being so constituted as to prevent a tilting movement of the door on the lifter, movable means for supporting 'the lifter which means are so constituted4 as to prevent a tilting movement ofl the lifter relatively to the door frames, means for retracting the lifteron the supporting means to withdraw the door fromthe frame, and'means for `moving the supporting means together with the lifter and door sidevvise to expose the mouth of the opened ,coking chamber.

2. A device 'of the character described,

comprising an oven having a pluralityol horizontal coking chambers, door frames at the mouths of said chambers, doors fitted into said frames' and provided at their front with engaging means, a lifter adapted to travel in front of said doors andv provided with means adapted to successively coperate With the engaging means of the doors, said engaging means and means on the lifter being so constituted as to. prevent va tilting movement of the door on the lifter, movable means for supporting the lifter which means are so constituted as to prevent a tilting movement of the lifter relatively to the door frames, means for raising the lifter on said supporting means to ease a lifter-engaged door Within its frame, means for retracting thelifter on the supporting means to Withdraw the eased door from the frame, and means for moving the supporting means together with the lifter and door sidewise to expose the mouth of the opened.v coking chamber.
